Stolen bikes

The good thing about your bike is that the theft think it's too generic to be notice again, and it being a full suspension MTB, hardly an incommon bicycle in their next of wood, which also explain the number of spotting (as well as the bright paintjob).

keep looking for it, and always carry proof that it belong to you all the time, never pay them if they demand to be refunded otherwise they won't learn.

Hopefully you're right there. I've photocopied my proof of ownership and I'll hopefully catch them riding along Kingsland Rd again soon.
